What kind of cell detects a stimulus?

Sensory cells detect external stimuli such as light, sound, touch, taste, and smell. These cells are specialized in converting the energy from these stimuli into electrical signals that can be interpreted by the brain.


What are the first and last elements in a spinal reflex?

The first element in a spinal reflex is the sensory receptor, which detects a stimulus. The last element is the effector, which carries out a response to the stimulus.


The process of transduction usually begins?

Transduction usually begins when a sensory receptor detects a stimulus, such as light or pressure. The receptor then translates this stimulus into an electrical signal that can be interpreted by the nervous system.


What is the relationship between sensory adaptation and negative adaptation?

Sensory adaptation refers to the decreased response of sensory receptors to a constant stimulus, leading to reduced perception of that stimulus over time. Negative adaptation, on the other hand, involves a decrease in the overall response of a system to a stimulus due to prolonged exposure. While sensory adaptation is specific to sensory receptors, negative adaptation is a more general phenomenon that can occur across various systems in response to prolonged stimulation.


What is the first event associated with a reflex?

The first event associated with a reflex is the stimulus, which activates sensory receptors in the body. These receptors then send a signal to the spinal cord, bypassing the brain to produce a quick response from motor neurons, resulting in the reflex action.

What structure detects the stimulus in the reflex action?

The stimulus is detected by temperature or pain receptors in the skin. These generate impulses in sensory neurons. The impulses enter the CNS ( Central nervous system ) through a part of the spinal nerve called the Dorsal root.

Does A reflex arc begins with a receptor at the end of a sensory nerve?

No, a reflex arc begins with a receptor that detects a stimulus and sends a signal through a sensory nerve to the central nervous system.


What are phasic and tonic sensory receptors?

Phasic sensory receptors are specialized nerve endings that rapidly adapt to a constant stimulus, such as the touch receptors in the skin. Tonic sensory receptors, on the other hand, do not adapt as quickly and provide continuous information about a stimulus, like the proprioceptors that sense body position.


The process of transduction usually begins?

Transduction usually begins when a sensory receptor detects a stimulus, such as light or pressure. The receptor then translates this stimulus into an electrical signal that can be interpreted by the nervous system.


When the stimulus intensity is increased what changes?

When the stimulus intensity is increased, the sensory receptors are more strongly activated, leading to a stronger signal being sent to the brain. This can result in a perception of increased brightness, loudness, or other sensory qualities, depending on the specific sensory system involved.


What process occurs as specialized receptor cells in the retina respond to only some features movement colors or edges of each stimulus?

sensory reduction


How does information travel along the axon of a sensory neurone?

the receptor detects the stimulus and the sensor neurone sends it to the CNS (central nervous system


Muller's doctrine of specific nerve energies describes a form of coding?

Specific nerve energies refers to the idea that sensory nerves are specific to the type of stimulus they can detect and transmit to the brain. It suggests that it is the nature of the nerve signal itself, rather than the external stimulus, that determines the quality of our sensory experiences. This concept highlights how our brain interprets signals from different sensory nerves as distinct sensations.


What are the very first of the three steps basic to all sensory systems?

1. Recieve stimulus 2. Transform stimulus 3. Deliver stimulus
